or do you extend part sections to reduce wear and stiffen the pole? If you see what i mean.
If you have to do this then you have a pole not designed for the job or you bought cheap rubbish or both

Mine? fully extended sections every time (apart from minor adjustments for specific height). solid, exclusive use & abuse for 14 months on tops & bottoms.
Clamp adjustment? one clamp half a turn

not bad eh?
